Application filed November 20, 1913. Serinal No. 802,035.

T0 aZZ lwhomy it may concern:

Be it known that I, ERNEST S. GroLDY, a citizen of the United States, and a resident of .lladdonlield, in the county of Camden, Slate of New Jersey, have invented certain new and useful Improvements in Tooth- Brushes and the like, of which the following is a specification, reference being had to the accompanying drawing.

'l`his invention especially relates to that class of tooth brushes in which the brushhead is adapted to be detached from its operative position upon thehandle and inclosed within the latter when not in use, and among the principal objects of my invention are to provide an improved means for securely attaching the brush-head to the handle when in operative position thereon, and to provide a means of attachment or locking means which shall prevent both longitudinal and rotative movement of the brush-head with respect to the handle, and which shall be of such nature as to be readily and quickly operated.

Further objects of my invention are to provide a means for attaching the brushhandle which shall be neat and ellicient and which may be readily constructed and at a minimum expense;

My invention further includes all of the various other objects and novel features of construction and arrangement hereinafter more delinitely specified.

In the accompanying drawing, in which one form of my invention is illustrated, Figure 1 is a side elevation of the brushhead and handle in operative position: Fig. 2 is a side elevation'of the handle, the brushhead being shown in broken lines disposed within the handle; Fig. 3 is a top plan view of the brush-head; Fig. Il, an end view of the handle with the parts substantially in the position shown in Fig. 2, Fig.v 5 is an end view of a portion of the iocking means removed from the handle; and Fu 3, a side elevation of the brush-head, pa 'tially in central vertical section.

Referring to the drawing, the handle 1 of the device may be formed, preferably in approximately the shape indicated, of celluloid, larisian ivory, sheet metal, or any other suitable material and may be so shaped and of such a size as to readily contain the brush-head when not in'use, as shown in Fig. 2. The lower part of the handle at one end, may preferably be lextended somewhat beyond the maiii' portion thereof to form a cylindrical projection 2, hereinafter termed the socket A'the central longitudinal axis of which may preferably be approximately co-incident with the'plane of the surface of the interioiiof vthe bottom portion of the handle, althoiiglrthis is not essential. The socket 2 may be formed innny desired manner and preferably integral with the rest of the handle. In practice, however, it has been found that the flat sheet from which the handle is generally made may be readily shaped in such manner that when the handle is formed up, the socket '2 may be formed at the same time and with a minimum of operations and expense. Of course if the handle is molded or otherwise made from some plastic composition instead of from a llat sheet of material, the mold may be so constructed as to produce the desired form,- or,'if desired, the socket 2 may be formed separately fromy the body of the handle, and united thereto in any suitable manner, as byA solder or cement.

The brush-head having the usual bristles G, may also be constructed of any desired material, although celluioid, Parisian ivory, or similar compositions are well fitted for this purpose rlhe brush-head may be pro-v vided with a suitable shank 8, which may preferably be cylindrical in forni, tremlty of the shank being of slightly less external diameter than that portion nearer the brush-head 5, so as to form a shoulder 9. The shank may be iXedly secured to the bruslnhead in any desired manner, and is provided on its upper side with a longitudinal, preferably oblong, slottll for a purpose to be hereinafter described Pivoted adjacent to the tubular portion or socket 2 of the handle, is the catch 15, whichl may preferably be formed of sheet metal substantially in the shape shown. This catch is substantially semi-cylindrical in cross section, and is pivoted to the handle 1 by means of a horizontal pivot 1G, passing. through the socket Q and through dependent' baclm'ardly extending portions of the catch so that the latter .may be rotated about the pivot 16 in a substantially vertical plane.

the eX- of the socket 2 when the catch is opened or- .the portion trally disposed downwardly projecting dog 24, which may with the body metal composing the same in such manner that the dog may be-bent inwardly substantially to the center of the catch as shown, so

preferably be formed integral thatl it. will lie substantially in a verticalplane passing through the vcentral longitudinal axis of the socket 2. Of course the dog may be formed separately from the body of the catch and secured thereto by solder or riveting or in, anyother desired manner, but in practice it has been, found preferable to form it' integral -with the body of the catch in th'e manner described. The forwardl end of the catch if desired may be slightly turned up to form the thumb piece 26.

The socket 2 of the handle is provided on its upper side with a suitable preferably oblong, slot 28, of a length and width slightly greater than the respective length and thickne'ss of the dog 24, lation to the catch 15, that when the same is rotated about its pivot 16, to assume the position shown in 1, the dog 24; will enter the slot4 28 and proJect therethrough into the interior of the socket 2. If, while the catch is in the position-'shownin Fig. 2,'the shank l8 of the brush-head 5 be inserted in the socket 2 of thehandle 1, the shank 8 beingV of a diameter to form anice fit within the socket, and the shoulder 9 being operative to limit the distance it may be inserted therein, and the slot 11 alined with the slot28, it will be evident that when the catch is closed to the position shown in Fig. l, the dog 24, will pass through both the slot 28 and theslot 1l, the latter being of a suitable size to form a nice fit in all directions with the dog 24. Furthermore, the` catch 15 will be securely maintained in closed position as shown in Fig. 1 by the engagement of the ears A2O with the exterior of the socket 2, which, as already stated, are of suflicient length to come slightly below the point of greatest diameter of the socket 2 and thus partially surround the same, while, however, being so adjusted as to be capable of being forced or sprung past the point of greatest diameter closed by the operator. The former operation may readily be acomplishedy by pressing down upon the catch when in the position shown in Fig. 2, and the latter, by inserting the thumb-nail beneath the thumb piece '26 oflthe catch by cutting the and so disposed with re-A and raising. the catch out of its closed position, asl shown in Fig. 1.

It will thus be evident that the brushliead is securely maintained in operative position upon the'handle when the catch is in closed position, and is prevented both from rotative movement about the central longitudinal axis of the socket 2, as well as from longitudinal movement with relation to the handle 1, while, however, being capable of ready detachment from the handle by raising the catch l5, thus permitting it to be. disposed within the handle, where the'bristles will be protected and kept from contact with foreign substances. At such times the catch is generally left in closed position from which it is raised to permit the insertion of the shank 8 when it is desired to place the brush-head in operative position upon the handle.

While 1 have Aherein described my invention'as applied in connection with a toothbrush, it will be evident that the use to which the brush may be especially adapted is immaterial, and that the invention may be applied" with equal success to other brushes, Such aS nail brushes. Furtherm re, I do not desire to limit my invention to the exact form herein shown and described, as it will be evident that various changes may be made in the details of construction and arrangement of the various parts of the device, without departing from the spirit and scope of the' invention as defined in the appended claims. l

Having thus described my invention, I claim and desire to protect by Letters Patent of the United States 1. In a toothbrush, the combination with a handle having a space adapted to contain the brush-head and an outwardly extending cylindrical socket, of head having a shank provided with a slot, and means movable upon said handle adapted to partially surround said socket and having a depending portion adapted to enter said slot when the brush-head is in operative position upon Said handle.

2. In a toothbrush, the combination with a handle having a space adapted to contain not in use, a detachable brush-head, ami my hand this 19th day of November, A. D. means separate from said handle pivotally 1.91.3.

mounted thereon and adapted to partially embrace said handle operative to maintain said bmah-head Xedly positioned. upon said handle.

' In Witness whereof have hereunto set ERNEST S. GOLDY.
